Ja090xp0 thin-section sealed four-point contact ball bearing for textile machinery Product model:ja090xp0 Brand name:frb; Material: gcr15, gcr15simn; Bore size: 228.6 mm; Outside diameter: 247.65 mm; B :12.7 mm; Weight:0.535 kg Thin-section sealed four-point contact ball bearing is also designed for mounting shaped ring both sides on the basis of thin-section four-point contact ball bearing .We have many options for the structural form of the shaped device. Others performance are the same with thin-section four-point contact bearing, except for the low rotational speed. Frb thin section bearings were designed to fill the need for a fully hardened, thin-section, anti-friction bearing-a need resulting from the modern design concepts of simplicity, miniaturization, weight reduction, and compactness being applied to a wide variety of rotating devices. -
